On February 21, Horse News posted an article about the possibility of two Equestria Girls sequels on the way. The author, Liki Weaks, cited a note on a title card as evidence to the possibility of multiple Equestria Girls sequels.
Earlier today, we learned that this was not just a slip-up by the editing department.
Equestria Girls 3 has indeed been confirmed, at least in book form.
The description is incredibly vague, telling us that there will be an adventure at Canterlot High. The title and cover art has not even been finalized, so it may in fact go through some changes between now and publishing. We also think it will feature the main six ponies of the show, because the obvious apparently must be stated.
The book can currently be pre-ordered on Amazon and will be written by the same author as the Rainbow Rocks book: http://www.amazon.com/dp/0316247774
For now, sound the alarms! Remember when you all thought Rainbow Rocks was just a book? Remember when Horse News didn't listen to their own article? THERE'S NO STOPPING THIS NOW!
